OK, so this is a little embarrassing. Last night I wrote that it might take a while for Ultimate Rewards Mall points to post if you bought “free after rebate” software in order to get thousands of Ultimate Rewards points for free at Staples.com. Well, this morning I found that all 4X points have already posted! And, yes, I paid with my American Express Reserve card.
I bought the software on Thursday. Hopefully your points will post soon too!
